1. 1. Increasing the diodicity of ceramic Tesla valves by exploiting the design freedom of additive manufacturing : A study in design optimizations of Tesla valves for ceramic 3D printing

   Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Udit Sharma; [2024]
   Nyckelord :additive; manufacturing; Tesla; valve; ceramic; 3D; printing;

   Sammanfattning : The work presented in this thesis was conducted at Uppsala University and at Fraunhofer IKTS, Dresden. The thesis aims to study design optimizations for increasing the diodicity and thereby performance of a Tesla valve, a type of “no moving parts” (NMP) valve, through design freedoms offered by ceramic additive manufacturing.

3. 2. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Ahsan Ali; [2023]
   Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

4. 3. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

   M1-uppsats, Högskolan i Gävle/Maskinteknik

   Författare :Adam Norell; Darav Hajo; [2023]
   Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

   Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER

5. 4. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :LINDA YANG; [2023]
   Nyckelord :Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

   Sammanfattning : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. LÄS MER

7. 5. A comparative study on anapproach to print Industrial Toolsvia Additive Manufacturing for Volume Production from Technical, Economic, and Environmental aspects

   Master-uppsats, KTH/Produktionsutveckling

   Författare :Purav Mukesh Thaker; [2023]
   Nyckelord :;

   Sammanfattning : The thesis explores a path to use Additive Manufacturing as an approach for volume production of Industrial Technique Business Area Tools, addressing the challenges of manufacturing complexity, low volume demand, and quality control for both Atlas Copco Industrial Technique industrial tools (Tool 1 & Tool 2). This study is done in cooperation with Atlas Copco Industrial Technique, comparing the technological, economic, and environmental performance of AM versus the current manufacturing approach from a round bar.
